Product Options


MASS 6000 mass flow transmitter is based on the latest developments within digital signal processing technology engineered for high performance, fast flow step response, fast batching applications, high immunity against process noise, easy to install, commission and maintain. The MASS 6000 transmitter delivers true multiparameter measurements i.e.: Mass flow, volume flow, density, temperature and fraction flow.

The MASS 6000 Ex d transmitter is manufactured in stainless steel (AISI 316L) and able to withstand harsh installation conditions in hazardous applications within the process and chemical industry. The conservative choice of material guarantees the user a low cost of ownership and a long trouble-free life-time. The Ex d can be compact mounted on all sensors of type MASS 2100 DI 3 to DI 40, and can be used in remote version for all types of MASS 2100.


The mass flow transmitter is designed in an Ex d compact stainless steel enclosure which can be compact mounted on the MASS 2100 sensor range DI 3 to DI 40, and remote mounted for the entire sensor series. The MASS 6000 Ex d is available as standard with 1 current, 1 frequency/pulse and 1 relay output and can be fitted with addon modules for bus communication.

  • Flameproof "d" enclosure
  • Enclosure stainless steel, IP67/NEMA 4X as compact and IP66/NEMA 4 as remote
  • Supply voltage 24 V AC/DC
  • MASS 6000 Ex d is ATEX approved together with all MASS 2100 sensors

Heating Jacket

All the sensors MASS 2100, DI 3 to DI 40, can optionally be equipped with a heating coil in order to prevent solidification of sensitive fluids during down-time or periods between discontinuing processes. This provides an alternative to the costly electrical heating normally used, as it gives the freedom to choose either hot water, superheated steam or hot oil, to maintain a constant temperature inside the sensor.


  • High accuracy better than 0.1% of mass flow rate
  • Large dynamic turn-down range better than 500:1
  • Single continuous tube design, with no internal welds, reductions or flow splitters offers optimal hygiene, safety and CIP cleanability for food & beverage and pharmaceutical applications
  • Markets biggest wall thickness, ensuring optimal life-time and corrosion resistance and high-pressure durability
  • Densitometer performance available through a density accuracy better than 0.0005 g/cm3 with a repeatability better than 0.0001 g/cm3
  • Full bore design provides lower pressure loss due to same internal
    diameter throughout the entire sensor.
  • Balanced pipe design with little mechanical energy loss, ensures optimal performance and stability under non-ideal and unstable process conditions (pressure, temperature, density changes etc.)
  • 4-wire Pt1000 temperature measurement ensures optimum accuracy on mass flow, density and fraction flow
  • Multi-plug electrical connector & SENSORPROM enables true "plug & play". Installation and commissioning in less than 10 min.
  • Intrinsically safe Ex-design ia IIC as standard, making service in hazardous area possible without having to demount the sensor if a compact Ex d transmitter needs service
  • Sensor pipe available in high-quality AISI 316L stainless steel W 1.4435 or Hastelloy C22 W 2.4602 offering optimum corrosion resistance
  • Centre-block design decouples process noise from the environment such as vibrations, pulsations, pressure shocks etc. making installation flexible and versatile
  • Rugged and space-saving sensor design in stainless steel matching all environments
  • Uniform sensor interface matching all transmitter versions at the same time whether it is compact IP67/NEMA 4X, compact Ex d or remote installation, one sensor fits all
  • High-pressure program as standard
  • Sensor calibration factor is also valid for gas measurement
